I'm hopefully going Antelope hunting this year with my dad. My question is this... I own a Ruger M77 30.06. I know this is a great all-around caliber for deer, elk, carabou, what ever. I also know it is probably a little heavy for goats. I have an itch to buy a flatter shooting new gun and am thinking of either a 7mm or a .270. I know the .270 would be a good shooter, but I guess what I am wondering is if the 7mm would be a better choice as a flat shooting long range rifle as well as an improvement over the 30.06 for elk for future hunts.
